No. Activities are a set of "components" on the page. A Place, by definition, describes the "location" within the app, which you can interpret as being the "state" of the app, thus the "state" of the activities (it's rather the other way around though: you navigate to some place, and activities will construct their state from the current place) Have a look there for more details: http://tbroyer.posterous.com/gwt-21-places, http://tbroyer.posterous.com/gwt-21-places-part-ii and then tbroyer.posterous.com/gwt-21-activities -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
